Therefore, for mixed models, we typically recommend to update the linked model only after the modeling has been fully finalized. You For certain types of models, you may also consider developing the SAP2000/Bridge object and the SAP2000 model in separate files and merge them prior to the final analysis. This way you do not need to worry about the connectivity problems each time the SAP2000/Bridge object is updated.
...
Mixed models are typically used to apply model features that is currently not available in the SAP2000 bridge object. Typical examples include (as of V14.02.0):
- Modeling a special type of bent.
- Modeling custom bearing layout (by default, the program places one bearing under each web).
- Applying special types of loads to the bridge object - breaking forces, settlement of support, etc.
With future updates of the program the need for mixed modeling should gradually vanishWe gradually plan to enhance the parametric bridge model definition so that the need for "manual interventions" is minimized as much as possible.
